PURPOSE
This Service Bulletin provides instructions to reprogram the ETACS-ECU with the latest software.

BACKGROUND

After about 30 minutes has elapsed with the ignition switch accessory in the "ACC"
position, the function automatically cuts out the power for the audio system and other
electric devices that can be operated with that position.
Due to improper ETACS-ECU programming the signal that disables ACC auto cut
function may not operate. Software changes which modify the logic of the ETACS-ECU
will allow the auto power off function to operate as designed.
Please reprogram the software upon customer complaint basis.

AFFECTED VEHICLES

2020-2021 Outlander Sport (VIN Cut-off JA4APUAU7MU022501)

ATTENTION:
 Turn off all electrical devices to minimize the vehicle's electrical load. Also use an
external power source to ensure that the vehicle battery maintains the specified
voltage during reprogramming. Low voltage of the auxiliary battery may cause
incomplete reprogramming and should that occur the ECU may require replacement.
 Write down all the customer’s electrical device settings such as A/C and radio before
reprogramming and restore them after reprogramming
 Connect the MUT-3 to an AC power source to prevent internal battery discharge.
 Before using, make sure the USB cable and MUT-3 main harness are not damaged.
 Do not perform maintenance work in the engine room during reprogramming.
The cooling fan may operate while reprogramming.
 Check the All DTC after reprogramming and erase them (if any).

ECU REPROGRAMMING CHART

SOFTWARE/MEDIC VERSION VERIFICATION PROCEDURE
1.

Verify that the ETACS-ECU has not already been updated to the latest S/W number in the table
above. If the ETACS-ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the ETACS-ECU with the latest database (e.g., N410001501)
includes all past and current reprogramming for TSBs of affected vehicles. It is not
necessary to reprogram the ETACS-ECU for each previous TSB.

For MEDIC 3.5/4 users only: (MUT-III SEV users go to step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update 769 or higher.
If your MEDIC 3.5/4 update is at least 769, continue with the Reprogramming Procedure.
If your MEDIC 3.5/4 update is below 769 update your MEDIC as follows:

3.

Select the MEDIC 3.5/4 Admin tab and click on “Updates”.

4.

If the MEDIC update screen advises updates are available, click the “Begin” button. After all updates
are complete, GO TO THE REPROGRAMMING PROCEDURE.

5.

STANDALONE MUT-III SE SCAN TOOL VIEWER (STV) ONLY: (MEDIC 3.5 USERS – GO TO THE
REPROGRAMMING PROCEDURE). Verify that your MUT-III SE has the most current version of the
reprogramming database from the MUT-III SE Main Page.
a. Press the MUT-III SE STV icon.

b. Press the Reprogramming button once the vehicle information is entered.

c. Press "ECU Reprogramming (SDB)" button.

d. Confirm that the database number displayed above the chart is N410001501 or higher.
i. If the database number displayed on your MUT-III SE is N410001501 or greater,
continue to the next section.
ii. If the reprogramming database number displayed on your MUT-III SE is lower than
N410001501, then the MUT-III SE database needs to be updated.
iii. Once the database number is confirmed, hit the Home button to go back to the
System Select screen.

REPROGRAMMING PROCEDURE
! CAUTION

To ensure that the vehicle battery maintains 12V during the procedure, hook- up a
battery charger to the vehicle during the procedure.

NOTE: VCI Stand−alone reprogramming is not available for this procedure. The laptop/tablet and
the VCI must remain connected for the entire procedure.
1. Connect the equipment as follows:
NOTE: VCI Lite and MEDIC 4.0 Toughpad shown for illustration purposes only.

Data Link
Connector (Blue
End)
MUT−III SE
Main Harness

USB Cable

•

Turn the MEDIC PC/tablet on. If the battery
indicator in the lower right-hand corner of
the screen does not show a full charge, it is
recommended that either the battery be
charged prior to beginning or be used with
the A/C power adaptor connected.

•

Connect the USB cable to the VCI/VCI Lite.
When the laptop/tablet displays the MUT-III
SE main screen, connect the USB cable to the
device.

•

Connect the MUT-III SE main harness with the
blue DLC connection to the VCI/VCI Lite.
Connect the blue connection of the MUT-III SE
main harness to the vehicle's data link
connector.

•

For VCI only (p/n MB991824): Turn the VCI
power switch ON. Verify that the indicator
lamp in the upper right corner of the screen
is green.

VCI Lite

! CAUTION

DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS DURING THE REPROGRAMMING PROCESS
AS IT COULD CAUSE THE CONTROL UNIT TO LOSE DATA. IF THE USB CABLE IS DISCONNECTED
DURING THIS PROCEDURE, A WARNING MESSAGE WILL DISPLAY.
NOTE: Due to limited space it may be easiest to connect battery charger cable onto ground
point.
2. Turn the ignition switch to the “ON” position.
